The Galileo Venus encounter

Galileo's instruments obtained a broad range of planetary measurements during the spacecraft's Venus encounter on February 10, 1990. The instrumentation brought to bear encompassed UV spectra, limb haze studies, and particles-and-fields experiments. These data, in conjunction with ground-based observations conducted during the encounter, have yielded accurate information on the Venus plasma environment, cloud patterns, and the possibility of interpreting certain impulsive events as lightning.
